How to add AwesomeFontFX Icon Pack to JavaFX Project in IntelliJ IDEA?

Question

I am creating a mini-JavaFX project and wanted to use the Awesome Font Icon Pack.I loaded the fontawesomefx-8.9 using the Scenebuilder and opened the FXML in it and loaded two icons in it, also added the JAR file in External Libraries in IntelliJ but when I run the code it gives a ClassNotFoundException for de.jensd.fx.glyphs.fontawesome.FontAwesomeIconView. What should I do?

I removed the two Icons and the code runs fine. I searched many places but it only showed to add the JAR files to external libraries and nothing. I am using JDK 12 , JavaFX 12 and Scenebuilder 11.0.

FXML File

<?xml version="1.0" encoding="UTF-8"?>

<?import de.jensd.fx.glyphs.fontawesome.FontAwesomeIconView?>
<?import javafx.geometry.Insets?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.layout.ColumnConstraints?>
<?import javafx.scene.layout.GridPane?>
<?import javafx.scene.layout.RowConstraints?>

<fx:root alignment="center" hgap="10" type="GridPane" vgap="10" xmlns="http://javafx.com/javafx/8.0.171" xmlns:fx="http://javafx.com/fxml/1" fx:controller="sample.Controller">
   <children>
      <Button mnemonicParsing="false" text="Click Me!!!">
         <opaqueInsets>
            <Insets left="5.0" />
         </opaqueInsets></Button>
      <FontAwesomeIconView glyphName="CIRCLE" />
   </children>
   <columnConstraints>
      <ColumnConstraints />
   </columnConstraints>
   <rowConstraints>
      <RowConstraints />
   </rowConstraints>
</fx:root>

Controller Class

package sample;

import javafx.fxml.Initializable;

import java.net.URL;
import java.util.ResourceBundle;

public class Controller implements Initializable {

    @Override
    public void initialize(URL url, ResourceBundle resourceBundle) {

    }

Module-Info.java

module Practice {
    requires javafx.controls;
    requires javafx.fxml;

    opens sample;
}

Main Class

package sample;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception{
        Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        primaryStage.setTitle("Hello World");
        primaryStage.setScene(new Scene(root, 300, 275));
        primaryStage.show();
    }


    public static void main(String[] args) {
        launch(args);
    }
}

Answer 1

Since you are using Java and JavaFX 12, you should use a valid FontAwesomeFX version: 11.0.0.

You can find it here: https://bintray.com/jerady/maven/FontAwesomeFX/11.0.0

If you are using Maven or Gradle, you can just include the FontAwesome dependency:

dependencies {
    implementation "de.jensd:fontawesomefx-fontawesome:4.7.0-11"
}

That will also include de.jensd:fontawesomefx-commons:11.0 .

If you don't use Maven/Gradle, you will have to download them from here and here , and include them in your project.

Next step: since you have a modular application, your module descriptor should contain all the modules that your project requires .

Therefore your module-info should include the fontawesome module:

module Practice {
    requires javafx.controls;
    requires javafx.fxml;
    requires de.jensd.fx.fontawesomefx.fontawesome;

    opens sample to javafx.fxml;
    exports sample;
}

Now your project will have all the required dependencies and will work.
